Correction of micronutrient deficiencies is one of the priority directions in the practical work of a pediatrician
Abstract
Micronutrients (vitamins, minerals, micronutrients) are essential for the normal functioning of the body. The problem of vitamin deficiency leads to the risk of alimentary-dependent diseases. The reasons of inadequate provision with vitamins and minerals are given: unbalanced irrational nutrition, the quality of the products themselves, the nutritional value of which is significantly reduced with the use of modern production technologies. It is noted that the biological availability, i.e. the degree of absorption of vitamins from different products, varies widely from 5 to 80% of their total content in the product. In order to concretize the diverse physiological role of micronutrients as an important component of various enzyme systems and metabolic catalysts, the authors summarize the literature reflecting the importance of vitamins of group B, ascorbic acid, retinol, vitamin D and their functional correlations, as well as the need for a balanced and harmonious approach to their dosing. The problem of negative influence of deficiency of microelements on the structural and functional condition of various organs and systems, on morbidity, linear growth, development of various skills and psycho-emotional sphere of the child is covered. Attention is paid to the danger of micronutrient deficiency, which often remains unrecognized for a long time, because its clinical manifestations are not specific and can be observed in various diseases. However, the excess of individual micronutrients also disrupts the physiological and biochemical processes in the body. The vitamin requirements of healthy infants correspond to the amount of vitamins consumed daily with the mother’s milk: From 4-6 months of age, the provision of vitamins to the child is significantly affected by the introduction of complementary foods, for children from 1.5 to 3 years of age, the daily dose of vitamins and minerals in the VMC should not exceed 50% of the daily physiological needs, and for children over 3 years of age should not exceed 100% of the daily physiological needs for vitamins A, D and micronutrients (selenium, zinc, iodine, copper, iron), and 200% for water-soluble vitamins. An example of balanced and complete composition of vitamin complexes Multi-Tabs is given.
